Trent Sequence

November 2015

This is a list of measurements in metres taken from Google Earth showing the bridges (bridge widths and old bridge names in bold) and any narrow points (small type) on the River Trent.

The river itself is generally much narrower than the old stone bridges that would have been built to carry any flood water. If the river is too narrow for a flood, water will fill the flood plain - obviously.
The problem is that it is against the law to widen the river - see “Why Britain floods” on the main web site.

The river in Stoke has several buildings restricting the river and some of the bridges are too narrow. I cannot see any old bridge to give a necessary width. They should be at least be bigger than Norton Green at 9m.

Note how the river (including Colwick sluice in Nottingham) is much narrower than the bridges. Some of the newer bridges are ridiculously small.

The question marks show where there may be a problem, basically most of the river. If the river banks are low the land will flood, if the banks are high flooding will occur elsewhere. The river width should bear some resemblance to the bridges and increase in size as it proceeds downstream.

All the river below the Tame at 22 to 83m and is nowhere near what it should be I.e. 75 to 135m.

Kelham and Newark should be added together.

The rail bridges show the width of the flood plain.

All these sites can be found on Google Earth but what really matters are the old bridge widths and the river widths, they should bear some resemblance. The river needs clearing/dredging as necessary but I am afraid this is not allowed therefore the flooding will increase as the river blocks up.
